Trurapi vs Novorapid

I am coming to the end of my Trurapi insulin and have for now to use Novorapid due to the Trurapi having a national shortage (no pharmices around my area have it either) today when I went for my other prescription I was given another lot of novorapid, the girl asked me have you started using novorapid yet. I said no because I have 3 pens of Trurapi left before I start the Novorapid. She advised when I finish using this pen to start on the Novorapid to see if there is any change and to get in touch with my diabetc team if there is (sound advice) then took the novorapid backas they will keep it for me
OK am I liable to notice much difference they are both the same (Aspart) ?
I am a little concerned of my number changing after using trurapi for over a year ( the novarapid pens do seem cheaper made than the Trurapi ones is the only thing I can say for now) and I hope they take the same needles (glucorx fine point 4 mm 31 gauge)
thank you
